The internal structure of the earth reflects the planets' early beginings. The inner most layer is called the core which is composed of mixtures of Iron (also known as alloys). The core is made up of a hard inner layer and a liquid outer layer. It is believed by scientists that the motion of the core contributes to the earth magnetic field.
The mantle is the layer above the liquid layer of the core. Scientists are inconclusive on whether the mantle is liquid or solid.
The crust of the earth is the most recognizable layer of the earth because we see it daily. The crust is a very thin layer made up of plates that are constantly moving. There are two types of the crust that can be found and they consist of oceanic crust and continental crust.
An earthquake may have a epicenter in North America, but the waves from the quake travel through the different layers of the earth and can be found on seismographs at different locations of the planet.
